Abstract

The invention provides an intelligent composite overwrapped pressure vessel relating to micro-nano sensors and a manufacturing method of the intelligent composite overwrapped pressure vessel, and relates to the technical field of manufacturing of intelligent overwrapped composite pressure vessels. The intelligent composite overwrapped pressure vessel comprises a composite overwrapped pressure vessel bottle body and a flexible sensor array. Through a flexible printed circuit, the number of wires is decreased, and arrangement of the wires is simplified; composites and the micro-nano sensors areintegrally formed, so that any tiny damage of a composite structure in the service process of the composite overwrapped pressure vessel is transmitted to the microstructures of the micro-nano sensorsin real time, the change of the residual resistance of the micro-nano sensors is shown, and great sensitivity is achieved. Compared with a traditional resistance strain gauge and a fiber grating sensor, the intelligent composite overwrapped pressure vessel has the advantages of large-deformation monitoring, high sensitivity coefficient, high service temperature, multi-directional monitoring and curved surface structure health monitoring and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing of intelligent composite material pressure vessels, in particular to an intelligent composite material pressure vessel involving micro-nano sensors and a manufacturing method. Background technique [0002] Pressure vessels are special equipment that is widely used in production and life and may cause high risks such as explosion or poisoning. Due to various problems in design, manufacture, installation and operation of pressure vessels in service, abnormal failures occur, resulting in sudden damage accidents. Compared with the all-metal pressure vessel, the composite pressure vessel has better mechanical properties, but its complex structure causes it to have more and more complex damage mechanisms in the process of manufacturing and service. In order to avoid the occurrence of extremely harmful accidents such as explosion and poisoning caused by the structural damage of the composite press...
